You may use a Data Query 2 template to create your data sets. To do this, open the "Data" menu from the sidebar, and click "Import a Data Query 2 template".
Then, select the template you wish to import by clicking the "Import" button. You may also use the search tool to find a template quickly.
Tip: this action will only import a template. In other words, if you edit a template in Data Query 2 after you've already imported it into the Dashboard Manager, the edits will not be reflected in the Dashboard Manager.
